Hi,
As you hold a Diploma in hotel management, you can apply for entry level positions in five star hotels in the core departments such as front office, housekeeping, food and beverage and food production.
If your performance is good, then you can easily become a supervisor in the next 2-3 years.
Many reputed five stars hotels like Oberoi, Taj, ITC, Hyatt, etc. conduct their own training programs for the employees who perform better and promote them to the next position after training.
All the best.

Yes, you can pursue Hotel Management after class 12th for your career.
